2017 Ford F150 Coolant Type – Ensuring Engine Longevity
To maintain your truck’s cooling system, the 2017 Ford F-150 requires Motorcraft Orange Prediluted Antifreeze/Coolant (spec WSS-M97B44-D) or the newer, backward-compatible Motorcraft Yellow (spec WSS-M97B55-A). Using the correct Organic Acid Technology (OAT) fluid is vital to prevent heater core clogging and water pump seal failure. This guide breaks down exactly which fluid to buy and how to service your system like a pro.
Every Ford truck owner knows that the F-150 is a workhorse, built to handle everything from the daily commute to grueling off-road trails. However, even the toughest 5.0L V8 or 3.5L EcoBoost engine relies on a steady flow of high-quality coolant to manage the extreme heat generated under the hood.
Selecting the correct 2017 ford f150 coolant type is one of the most important maintenance tasks you can perform to ensure your engine doesn’t suffer from premature wear. In this guide, I will draw on years of mechanical experience to help you navigate Ford’s specific requirements and the recent industry shift in coolant technology.
By the end of this article, you will know exactly which bottle to grab at the parts store, how to identify if your current fluid is failing, and the steps to perform a professional-grade flush in your own driveway. Let’s dive into the specifics of what keeps your Ford running cool.
Understanding the 2017 ford f150 coolant type and Specifications
When the 2017 F-150 rolled off the assembly line, Ford filled it with Motorcraft Orange Antifreeze/Coolant. This fluid is an Organic Acid Technology (OAT) formula designed to provide long-lasting protection for aluminum engines without the need for supplemental additives.
The specific engineering standard you need to look for on the bottle is WSS-M97B44-D. This specification ensures that the chemical inhibitors in the fluid are compatible with the gaskets, seals, and alloys used in your truck’s radiator and engine block.
However, there has been a significant update from Ford. They have largely phased out the Orange coolant in favor of Motorcraft Yellow (specification WSS-M97B55-A). This newer fluid is a Phosphated Organic Acid Technology (P-OAT) that offers even better corrosion protection and is fully backward-compatible with the original Orange fluid.
Motorcraft Orange vs. Motorcraft Yellow
If you head to the dealership today, they will likely hand you a gallon of the Yellow coolant. Do not panic; Ford has officially stated that Yellow can be mixed with Orange in 2017 models without issues. The Yellow formula was developed to address some of the “dropout” issues seen with the older Orange fluid.
While they are mixable, most experts recommend that if you are doing a full service, you should flush out the old Orange and refill the entire system with the newer Yellow P-OAT formula. This provides the most consistent protection for your heater core and water pump.
It is crucial to remember that “Yellow” is not the same as the old-school “Gold” coolant (G-05). Using the Gold specification in a 2017 F-150 can lead to chemical reactions that create a sludge-like buildup, eventually clogging your radiator and causing overheating.
Why the Correct Coolant Specification Matters
Modern engines, especially the turbocharged EcoBoost variants found in many 2017 F-150s, operate at much higher internal pressures and temperatures than older trucks. The 2017 ford f150 coolant type is engineered specifically to prevent cavitation, which is the formation of tiny bubbles that can pit and erode the metal of your water pump impeller.
If you use a generic “all-makes, all-models” coolant, you might be introducing silicates or borates into a system that wasn’t designed for them. These chemicals can wear down the mechanical seals in your water pump, leading to leaks that are expensive to repair.
Furthermore, the 2017 F-150 is known to have a somewhat sensitive heater core. The wrong chemical balance in your coolant can lead to scaling, where minerals and additives solidify and block the small passages in the core, leaving you with no heat during the winter months.
The Danger of Mixing Coolant Types
One of the biggest mistakes a DIYer can make is mixing OAT (Orange/Yellow) with IAT (traditional Green) coolant. These two chemistries are fundamentally incompatible. When mixed, they can form a thick, gel-like substance that stops all coolant flow.
If this happens, a simple drain and fill won’t fix it. You would likely need to replace the radiator, the heater core, and potentially the water pump to get the system clean again. Always verify the color and the specification before adding a single drop to your degas bottle.
If you bought your truck used and the coolant looks like muddy water or has a strange brownish tint, it’s a sign that someone may have mixed types or that the corrosion inhibitors have been depleted. In this scenario, a full chemical flush is the only way to protect your investment.
How to Check and Top Off Your F-150 Coolant
Checking your coolant is a simple task that should be done at every oil change. On the 2017 F-150, you don’t look at the radiator cap itself; instead, you check the degas bottle, which is the translucent plastic reservoir located near the front of the engine bay.
The degas bottle has “Cold Fill” markings on the side. Ensure the engine is completely cool before checking. The fluid level should be between the minimum and maximum lines. If it is low, you need to add the correct 2017 ford f150 coolant type to bring it back to the proper level.
When topping off, I always recommend using prediluted 50/50 coolant. This takes the guesswork out of the process and ensures you aren’t introducing tap water minerals into your cooling system, which can cause long-term damage.
Tools Needed for a Coolant Top-Off
- A clean funnel to avoid spills on your belts.
- A gallon of Motorcraft Orange or Yellow (Prediluted).
- A bright flashlight to inspect the degas bottle for cracks.
- A clean rag to wipe the area around the cap.
Never open the degas bottle cap while the engine is hot. The system is under significant pressure, and scalding hot steam can spray out, causing severe burns. Always wait at least an hour after driving before cracking the seal on that cap.
Step-by-Step Guide to Flushing Your Cooling System
If your truck has reached the 100,000-mile mark, or if you are switching from Orange to the newer Yellow fluid, a full flush is recommended. This process removes the old, acidic fluid and any debris that has accumulated over the years.
- Drain the System: Locate the plastic drain petcock at the bottom of the radiator. Place a large catch pan underneath and slowly turn the petcock. Ensure you have the degas bottle cap off to allow for faster draining.
- Flush with Distilled Water: Close the petcock and fill the system with distilled water. Run the engine with the heater on high for 10-15 minutes, then drain again. Repeat this until the water coming out is clear.
- Add Concentrated Coolant: Since there will always be some pure water left in the engine block, it is often better to add a calculated amount of concentrated coolant first, then top off with distilled water to achieve a 50/50 mix.
- Burp the Air: This is the most critical step. Air pockets can cause localized overheating. Ford engines can be stubborn, so use a no-spill funnel and run the engine until the thermostat opens and all bubbles stop appearing in the reservoir.
For those who use their trucks for heavy towing or off-roading, consider performing this service every 50,000 to 60,000 miles. Extreme heat cycles break down the chemical stabilizers in the coolant faster than normal highway driving.
Always dispose of your old coolant responsibly. Most local auto parts stores or recycling centers will take used antifreeze. It is highly toxic to pets and wildlife, so never pour it down a storm drain or onto the ground.
Coolant Capacity for 2017 F-150 Engines
The amount of fluid you need depends entirely on which engine is under your hood. Knowing the capacity helps you buy the right amount of 2017 ford f150 coolant type so you aren’t left stranded mid-flush.
The 3.5L EcoBoost typically requires about 16.5 quarts (15.6 liters) for a full system fill. The 2.7L EcoBoost is slightly smaller, requiring roughly 15 quarts (14.2 liters). If you have the 5.0L V8, expect to use about 15.9 quarts (15 liters).
Keep in mind that these are total system capacities. When you drain the radiator, you usually only get about 50-60% of the total fluid out. The rest remains trapped in the engine block and heater core, which is why multiple flushes with distilled water are so important for a clean result.
Pro Tip: The Refractometer
If you want to be precise, buy a coolant refractometer. This tool allows you to measure the exact freeze point and concentration of your mixture. It is far more accurate than the cheap “floating ball” testers and ensures your truck is protected down to -34°F and up to 265°F.
Common Challenges and Troubleshooting
Even with the right 2017 ford f150 coolant type, things can go wrong. One common issue owners face is a slow coolant loss without any visible puddles on the ground. This often points to a small leak in the turbocharger coolant lines (on EcoBoost models) or a failing degas bottle cap that isn’t holding pressure.
If you notice a sweet smell coming from your vents when the heater is on, your heater core might be weeping. This is often caused by neglected coolant that has become acidic and eaten through the aluminum core. Replacing a heater core in a 2017 F-150 is a massive job that involves pulling the entire dashboard.
Another thing to watch for is the “cooling fans on high” symptom. If your electric fans are screaming at full speed even when it’s not that hot outside, your truck might have an air pocket in the system or a faulty cylinder head temperature sensor. Always check your fluid level first when this happens.
When to Seek Professional Help
If you perform a flush and still experience overheating, or if you see “milkshake” looking oil on your dipstick, stop driving immediately. These are signs of a blown head gasket or a failed internal oil cooler. In these cases, a simple coolant change won’t help, and you need a licensed technician to perform a pressure test and combustion leak test.
Frequently Asked Questions About 2017 ford f150 coolant type
Can I use Dex-Cool in my 2017 F-150?
While Motorcraft Orange and GM’s Dex-Cool are both OAT-based and often share similar chemical profiles, they are not identical. For the best protection and to maintain any existing warranties, it is always recommended to stick with the Motorcraft Orange or Yellow that meets the Ford WSS specification.
What happens if I use the old Green coolant?
Using the old-style IAT (Inorganic Acid Technology) Green coolant will lead to rapid depletion of corrosion inhibitors. More importantly, if it mixes with the OAT fluid already in your truck, it can create a thick sludge that will ruin your radiator and heater core in a matter of weeks.
How often should I change the coolant in my F-150?
Ford’s official interval for the 2017 ford f150 coolant type is 100,000 miles for the first change and every 50,000 miles thereafter. However, many mechanics recommend a 60,000-mile interval for the first flush, especially if you live in a hot climate or use your truck for towing heavy loads.
Is it okay to mix Orange and Yellow Motorcraft coolant?
Yes, Ford has explicitly stated that Motorcraft Yellow is backward-compatible and can be mixed with Motorcraft Orange. This was part of a service transition to improve the longevity of the cooling system components and reduce the risk of heater core clogging.
Summary and Final Thoughts
Maintaining the cooling system of your truck is a relatively low-cost task that prevents multi-thousand-dollar repairs down the road. By ensuring you use the correct 2017 ford f150 coolant type—specifically the Motorcraft Orange (WSS-M97B44-D) or the updated Yellow (WSS-M97B55-A)—you are protecting your engine from the inside out.
Remember to always use distilled water for diluting or flushing, never mix incompatible types, and keep a close eye on your degas bottle levels. Whether you are cruising the highway or tackling a muddy trail, a healthy cooling system is the heartbeat of your truck’s reliability.
Take the time this weekend to pop the hood, check your fluid color, and ensure your F-150 is ready for the road ahead. Stay safe and keep your engine running cool!
